Connecting European snow cover variability with large scale atmospheric patterns
European snow variability with large scale atmospheric patterns
2010/9/10
Winter snowfall and its temporal variability are important factors in the development of water management strategies for snow-dominated regions. For example, mountain regions of Europe rely on snow fo...
Use of satellite-derived data for characterization of snow cover and simulation of snowmelt runoff through a distributed physically based model of runoff generation
satellite-derived data snow cover snowmelt runoff runoff generation
2010/3/5
A technique of using satellite-derived data for constructing continuous snow characteristics fields for distributed snowmelt runoff simulation is presented. The satellite-derived data and the availabl...
The physical basis for and the various methods of measuring the water
equivalent of the snow cover by means of gamma-rays survey from aircraft
are discussed.Problcms of mapping the water equivalent ...
